 5853 Wireless Glassbreak Detector Supplemental Information 
1. General Information 
The 5853 Wireless Glassbreak detector with 
Transmitter senses the sound of breaking plate, 
tempered, laminated, wired, coated and sealed 
insulating glass.  The self-contained detector includes 
a transmitter that can send alarms, tamper signals, and 
low battery messages to the control panel.   The 
sensor is compatible with 5800-series wireless 
hardware*, and is designed for continuous operation 
using two 3V lithium batteries (CR-123A or equivalent; 
included).    
Prior to installation, you must: 
•  Connect its batteries by removing the tab,  
•  Adjust the detector’s sensitivity, and  
•  “Enroll” the detector’s serial number.  
Refer to the following sections to install the 5853. 
This detector is both UL and ULC listed. 
*
Compatible control units for use in Canada require the use of 
listed RF receivers that have been subjected to compatibility 
analyses by Underwriters’ Laboratories of Canada.  Refer to the 
Installation Instructions for the control unit before installing 
burglar alarm components.
 
2.  Connecting Batteries/Initial Power Up  
To connect the batteries, remove the tab from the end 
of the battery holder.  The detector will start its power 
up sequence, in which both the LED indicators will 
illuminate for one second.  (The LED indicators are 
described later in these instructions.) 
3.  Adjusting Detector Sensitivity (Range) 
The 5853 has four sensitivity settings, which are set 
using the SENS1 and SENS2 DIP switches.  The 
settings are: 1) maximum; 2) medium; 3) low; and 4) 
lowest. By default, sensitivity is set to MAXIMUM.   
To change the detector’s sensitivity, use a small 
screwdriver to adjust the SENS1 and SENS2 switches, 
as shown in the table below: 
SENSITIVITY APPROX. 
RANGE  
SENS1 SENS2 
MAX 7.6m (25 ft) 
OFF OFF 
MEDIUM 4.6m (15 ft) 
ON OFF 
LOW  3m (10 ft) 
OFF ON 
LOWEST 1.5m (5 ft) 
ON ON 
 
4.  Enrolling Detector Into 5800-Series Receiver 
Before the control panel will recognize the 5853, you 
must program the device's serial number into the 
control panel.  This process, ("enrolling") is described 
in detail in the control panel's installation instructions.   
When programming the transmitter, specify: 
•  Input Type = 3 (Supervised RF) 
•  Loop Number = 1 
You can transmit the device’s serial number 
automatically or enter it manually.  To transmit the 
number automatically, momentarily activate the front 
tamper switch.  To enter the serial number manually, 
refer to the control panel’s instructions to enroll the  
serial ID number which appears on the product.  
5.  Selecting Installation Location 
The 5853 can be mounted on the ceiling or the wall.  
Choose a mounting location that is at least 2.1m (7 
feet) from floor and no more than 7.6m (25 feet) from 
the farthest protected glass.  Be sure the detector has 
an unobstructed line-of-sight to the protected glass!  
Before mounting the detector permanently, test it to 
ensure that it functions satisfactorily in the chosen 
mounting location.  Verify that the detector can detect 
glassbreak sounds, following the directions in the 
“Testing the Detector” section.  Ensure that the 5853 is 
within range of the receiver, following the instructions 
for the signal-strength test found in the control panel’s 
installation instructions.  (To send the signal required 
by the test, activate the detector's front tamper switch.) 
If the detector fails, relocate it and repeat both tests. 
6.  Mounting the Detector 
NOTE:  If using wall tamper and installing on dry wall 
(sheet rock),  position the detector so that the wall 
tamper is over a wall stud or ceiling joist, or use a 
drywall anchor so the tamper screw will not pull out. 
NOTE:  If the device is ceiling mounted, the end with 
the hole (Microphone end) should face the protected 
glass. 
 
To mount the detector: 
1.  Using the 5853 mounting holes as a template, 
mark mounting locations on the ceiling or wall. 
2.  If using the optional wall tamper, remove 
the batteries, then mark the wall tamper 
location through its mounting hole. 
3.  If required by the mounting location, install 
wall anchors for the mounting screws. 
4.  Secure the 5853 to the wall or ceiling, 
oriented so the microphone has the best line-
of-sight to the protected glass. 
5.  Reinstall the batteries if previously removed. 
6.  Close and secure the detector front cover. 
 
7.  Testing the Detector 
The detector should be tested at least once each year.  
Test the detector with the ADEMCO GBS-7 or FlexGuard 
FG-701 Glassbreak Simulator.   Other simulators will not 
give accurate indication of range.  
 
To enter the Test Mode with the GBS-7/FG-701: 
1.  Stand within 4.6 m (15 feet) of the detector. 
2.  Switch the GBS-7/FG-701 to ACTIVATE and 
MANual modes. 
3.  Point the front [speaker] of the glassbreak 
simulator towards the detector and press the 
red START button.   The simulator buzzes a 
short activation code. 
 
When the detector enters Test Mode, the green LED 
on the detector flashes about once per second.  If the 
green LED does not flash, move closer to the detector 
and repeat the procedure.  
 
To enter Test Mode manually: 
1.  Open the front cover. 
2.  Use a screwdriver to short the Test Mode 
pads on the PC board (see diagram on next 
page).   
3.  Close the front cover. 
The detector’s green LED blinks approximately once per 
second to indicate that it has entered the test mode.  
 
Testing the Detector (flex and audio signals): 
To test the 5853, do the following: 
1.  Place the detector in Test Mode. 
2.  Set the GBS-7/FG-701 switches to the TEST 
and FLEX positions. 
3.  Position the GBS-7/FG-701 near the farthest 
point of the protected glass, and point the 
speaker directly at the detector. If window 
coverings are present, close them fully and 
hold the GBS-7/FG-701 between the 
coverings and the protected glass. 
4.  Press the red START button. The simulator 
clicks on and starts an eight-second armed  
period. 
5.  Generate a flex signal by carefully striking the 
glass with a cushioned tool. The GBS-7/FG-
701 responds with a burst of glassbreak 
audio.   
If the detector receives both the flex and audio signals 
properly, its red Alarm LED lights for 5 seconds. (Red 
Alarm LED does not latch.) 
 
Testing the Detector (audio signals only): 
The GBS-7/FG-701 can also be used to test the 
detector’s ability to receive audio signals only.  See the 
GBS-7/FG-701 Operating Instructions for additional 
information.  When it receives the audio signal, the 
detector flickers its green Event LED. 
 
Exiting Test Mode: 
When you have finished testing, exit Test Mode by 
following the same procedure used to enter Test Mode.  
The detector automatically exits Test Mode five minutes 
after the last event is detected. 
 
8.  LED Indicators 
The detector is equipped with two LEDs: a green Event 
LED and a red Alarm LED.  When the LEDs are 
enabled during testing, they light in a variety of patterns 
to convey the detector’s operational status.  The 
following table summarizes the LED messages.  
(Please note that the LEDs are only enabled during 
Test Mode, and are inactive during normal operation.) 
CONDITION GREEN LED RED LED 
Power up  ON 1 second  ON 1 second 
Test Mode  Flash once per sec  OFF 
Test Mode, event detected  Flicker  OFF 
Test Mode, alarm  Flash once per sec  ON 5 seconds 
Low Battery *  Flash once per sec  Flash once per sec 
* If battery voltage drops too low, LEDs are no longer visible. 
9.  Cover Screw 
The front cover can be secured after installation.  To do 
so, remove the cover breakout flash (illustration on next 
page) and secure the front cover with a 6 mm (¼-in.), 2.9 
mm (#4) screw (supplied). 
10.  Maintaining Proper Operation 
To maintain the 5853 Glassbreak Detector in proper 
working order, please observe the following: 
Replace the batteries when the system indicates a low 
battery condition (refer to the control panel’s operating 
instructions.)  Be sure to replace the batteries with the 
proper type and voltage, and ALWAYS replace both 
batteries at the same time. 
The installer should inform the end user that fans, air 
conditioners, blowers, loudspeakers, or other sources 
of vibration and sound should not be introduced into 
the protected area after installation of glassbreak 
detectors.  If unavoidable, the end user must contact 
the alarm service company to re-adjust/re-test the 
equipment as needed.  Additionally, this device should 
not be relocated without the advice or assistance of the 
alarm service company.
